Digital power meter installation and use points

Digital power meter is a kind of multi-functional intelligent instrument with programmable measurement, display, digital communication and energy pulse transmission output, which can complete the functions of power measurement, energy measurement, data display, acquisition and transmission.
Digital power meter installation points
1). In the fixed distribution cabinet, select a suitable place to open a hole size mounting hole.
2). Remove the meter, loosen the set screw, and remove the retaining clip.
3). Insert the instrument into the instrument panel of the power distribution cabinet.
4) Insert the instrument's clip and secure the set screw.
Digital power meter use points
1. Before use, the meter needs to be powered on for 15 minutes.
2. Take care to prevent vibrations and shocks. Do not use it in places with excessive dust and excessive harmful gases.
3, the input lead should not be too long, if the measured signal input end is longer, please try twisted pair shielded wire.
4. If the signal is accompanied by high frequency interference, the low frequency filter should be tested online.
5. When unused for a long period of time, please supply electricity once every three months for not less than 4 hours.
6, long-term preservation should avoid direct light, should be stored in the ambient temperature -25 °C ~ 55 °C.
7. If the meter has no display, check the auxiliary power supply first and the voltage is within the range.
8. If the display is abnormal, check the input signal is normal and the signal terminals are tightened.
9. Unless the PT has sufficient power, the PT signal cannot be used as an auxiliary power source at the same time to ensure the normal operation of the instrument.
10. The current terminal screw in the CT circuit must be tightened to ensure reliable contact between the in/out line to avoid malfunction.
11. To verify the meter, check the instrument should be better than 0.1 in order to ensure the calibration accuracy.
